Title: Liquid crystal display device
Inventor: FUJINO HIRONOBU
IPC: G09F9/00
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a moving picture having higher picture quality to a user without incurring the reduction of luminance by flickering fluorescent lamps at high speed in synchronization with a scanning signal using a plurality of direct-under type fluorescent lamps as back lights. SOLUTION: Four direct-under type fluorescent lamps 110 are arranged at the back of an array substrate 101 as back lights. Respective lamps 110 are connected to a lamp driving circuit 111 and a driving voltage control circuit 112 flickering the lamps 110 in synchronism with the scanning signal of a panel and they are controlled by the circuits. Then, only roughly one fourth of the normal state of the panel can be lighted per one frame by lighting only one of the lamp 110 after a video signal is written on the panel.  As a result, the display state of the panel can be brought near the display state of the impulse type drive of a CRT from the display state of the hold type drive of liquid crystal and when the displaying of a moving picture is performed in this panel, the video signal of one frame before is not recognized and the reduction of the display quality of the moving picture due to edge blurs can be prevented.

Title: Address check system of loop transmission system
Inventor: SHIKIMO MASAYUKI
IPC: H04L12/437
Filed: 1983-07-21
Abstract: PURPOSE:To prevent the duplication of addresses by setting the address to each transmission controller and checking whether or not a transmission controller having the same address in a transmission system exists. CONSTITUTION:The transmission controllers fed with an address each in advance are connected to constitute a loop transmission line, each transmission controller transfers a received message to a next transmission controller and the message circulated in the loop transmission line is deleted at the transmission controller being the transmitting source. In order to check the duplication of each address, each transmission controller transmits an address train message at the activation of the own device and at the release of a detour, and each transmission controller receiving the address train message adds sequentially the own address thereto and transmits the result to the transmission line. The transmission controller being the transmitting source analyzes the address train in the circulated message and checks whether or not there is an identical address to the own address.

Title: Polarization preserving optical fiber
Inventor: YANASE TOMOO
IPC: G02B6/024
Filed: 1981-08-26
Abstract: PURPOSE:To prevent the increase of the coupling loss and to reduce the scattering loss, by attaching two glass rods having a larger coefficient of thermal  expansion than a glass rod at both sides of this glass rod and covering these glass rods with a glass tube. CONSTITUTION:A glass rod 13 having a high coefficient of thermal expansion is attached and melt-stuck at both sides of a glass rod having a core 11 and a cladding layer 12. These glass rods are covered with a glass coat 14. Then these glass rods are heated at a high temperature, and the rod 13 contracts greatly when it is cooled down to the normal temperature from a high temperature. As a result, the core 11 is turned into the double refractive glass. A polarization preserving fiber is obtained owing to the double refractive properties. In this case, the coupling loss does not increase with reduction of the scattering loss since the core 11 is kept circular.
